Psychiatric Toxicities of Cancer Therapies
The psychiatric effects of cancer treatments should receive renewed interest based on cancer treatment–related paradigm shifts and the ever-changing parade of new and improving cancer treatments. Precision medicine in oncology relies on personal molecular analysis and is touching patients in profound ways by providing prognostic information to guide treatment decisions. Due to enhancements in molecular sciences as well as data collection and management, the development of new treatments has accelerated in the field of oncology in particular. While there are many advantages to increasing the speed of drug development, ensuring that the psychiatric and psychological outcomes of these treatments are well understood remains a largely undeveloped area. This chapter introduces immunotherapies and targeted drug therapies, their mechanisms of action, and what is known about their psychiatric toxicity profiles. The chapter focuses on outlining the scientific rationale behind newer treatments such as immunotherapy and targeted therapies so that psychiatric consequences, perhaps yet to be discovered, may be further understood. Increased attention to patient-reported outcomes will hopefully enhance the identification of psychiatric consequences of immunotherapy and targeted therapies in oncology.
